What Our Gearhead(R) Experts Are Saying:"I packed the Espresso 2 Knee/Legwarmer for a ride where the forecast couldn't decide on a temperature, and the convertible length meant I only needed the one piece. The silicone gripper held it in place through a two-hour climb without a single slip."Some days, the weather can't commit, cold at the start, mild by the finish, and packing two separate warmers for that kind of ride gets old fast. Castelli solved that with the Espresso 2 Knee/Legwarmer, a single piece that stretches to cover the knee or extends further down the leg, depending on what the morning actually calls for. Thermoflex fabric supplies the warmth, built with a single-piece construction that skips the seams other warmers rely on, so there's nothing to rub through hours of pedaling. A silicone gripper at the top holds everything in place through hard efforts, and a raw-cut finish at the bottom keeps things comfortable once it's time to peel the warmer off and let the legs breathe.
